United States Patent aeaasse SHOE MACEEIE FOR SQLE AND HEEL BREAST FLAP LAYENG Edgar Haas, New York, N.Y., assignor to Herman ichgahe, Inc, Brooklyn, N.Y., a corporation of New Filed Feb. 16, 1959, Ser. No. 793,4se Claims. (Cl. 12-162) This invention relates to shoe machines, especially for ladies shoes having high heels, and more particularly to a machine for cementing the sole and heel breast flap of such shoes.

Ladies high heel shoes of better quality usually include a heel breast flap which i a direct continuation of the sole of the shoe. Originally, the heel portion of the sole was split to provide the desired heel breast flap, but in more recent manufacture the heel is attached first, and then the sole and heel breast flap are cemented in position. Ordinarily, this requires two operations, one for cementing or laying the sole, and the other for cementing or laying the heel breast.

The primary object of the present invention is to provide an improved machine for laying the sole and heel breast flap simultaneously.

A more particular object is to do this by motor means, preferably using fluid pressure. This requires the application of mutually transverse forces, that is, a force is needed generally perpendicular to the sole for cementing the sole, and another which is generally parallel to the sole for cementing the heel breast flap.

A further object is to interrelate or proportion these transverse forces, which may be done by using the same pressure fluid for both.

Another object is to regulate the relative rate of movement of the parts applying the transverse forces, lest a discrepancy in desired movement spoil the product, as by breaking a slender heel.

A further object of the present invention is to apply the same to a sole laying machine much of which is of known and proved type. One example of such a machine is that disclosed in my Patent No. 2,843,864 granted July 22, 1958, and entitled Shoe Sole Attaching Machine. Such a machine has a base, a head over the base, two upright cylinders in the base for two cementing stations, andaccurately adjustable cloclr timers to independently time the cementing operation on each of a pair of shoes. The mechanism affords a fast rise of the shoe pad carrying a lasted shoe until it reaches the stop posts on the head, thereby quickly freeing the hands of the operator to work on a second shoe when the first shoe has been properly positioned. This is done at low pressure, but then a slow forceful squeeze is applied at high pressure.

In accordance with the present invention, the main upright plunger carries a sole and heel breast pad, and

also a heel back pad which is movable toward or away from the first pad. The plunger further bodily carries a. small hydraulic actuator for moving the heel back pad horizontally.

In accordance with a further feature and object of the present invention, a low pressure movement followed by a high pressure squeeze is employed in both cylinders, and it here has an important additional advantage wholly apart from freeing the hands of the operator to work on the next shoe. This advantage is that the high pressure squeeze is applied only after all of the par-ts have assumed their proper position. Thus, the heel back pad moves against the heel under low pressure instead of high pressure, and if it comes into position before the lasted shoe has risen to the stop posts, no high pressure heel breaking force is applied. The shoe continues to rise.

in the shoe machine elements and their relation one to another as are hereinafter more particularly described in the following specification. The specification is accompanied by drawings in which:

FIG. 1 shows a machine embodying features of my invention;

FIG. 2 is a perspective view showing a ladies shoe mounted at one of the stations of the shoe machine;

FIG. 3 is a longitudinal section showing how the actuator and heel back pad may be applied to an adjustable shoe pad of known type;

FIG. 4 is a fragmentary elevation drawn to larger scale, taken at the right end of FIG. 3, but showing a modified form of the invention;

FIG. 5 is a flow diagram for the machine;

FIG. 6 is a perspective view showing the invention applied to a shoe machine of different comfiguration, and further showing the use of fluid filled pads; and

FIG. 7 is a transverse section through one of the pads.

Referring to the drawing and more. particularly to FIG. 2, the machine comprises a first fluid actuator the plunger of which is shown at 12, which exerts a pressure between the sole and the upper 14- of a shoe carried on a last 16, this pressure being in a direction generally perpendicular to the sole. The reaction is taken by adjustably fixed toe and heel posts 15 and 17. A second fluid actuator 20 exerts a pressure between the heel breast flap and the heel of the shoe in a direction generally parallel to the sole of the shoe. The machine further comprises means to apply pressure fluid simultaneously to both actuators, and this includes a flexible hose 22 leading from the base or" the machine to the actuator 20. Within the base of the machine there are connections to the cylinder of plunger 12 as well 'as to the hose 22.

The machine preferably includes a means to adjust the rate of movement of one actuator relative to the other, and in the present case there is a valve, the control handle of which is shown at 24, and adjustment of this valve may be used to vary the response of actuator 20, and therefore the relative response of the two actuators.

Referring now to FIG. 1 of the drawing, the two-station cementing machine there shown is of the type disclosed in my prior Patent No. 2,843,864 previously referred to, and FIG. 1 of the present drawing largely corresponds to FIG. 1 of that patent. There is a base 32 which may act also as a tank for hydraulic fluid. This is surmounted by a frame comprising uprights 34- and a top beam 36. The latter carries adjustable heel and toe posts for each of the two stations. One station is actuated by the hydraulic plunger 12 which is shown down, and the other by a plunger 4-2 which is shown raised. The plungers have platens which carry shoe pad boxes with molded rubber pads, and the lasted shoe is compressed between these pads and the heel and toe posts carried by beam 36. The stations are independently movable under control of separate foot treadles 44 and 46. Depression of a foot treadle causes its station to move from lowered or release position to raised or clamping position. The tank 32 is common to both stations and houses a common pump, and a common pressure relief valve which may be adjusted by means of a handle 47. The resulting pressure may be read on a suitable pressure gauge 48. In a typical case the a) pump is capable of building up an excess pressure but the pressure relief valve may be set at a lower figure, depending on the recommendations for and experience with the adhesive.

The time during which each station remains clamped is. independently determined by accurately adjustable electrical timing clocks 50 and 52. These have a suitable range, say from zero to 30 seconds. The head may also carry a safety switch controlled by a common safety bar 54, or two separate safety bars, one to release each station. The head 36 further carries a motor starter 56 for the motor which drives the hydraulic pump.

In the present machine the actuators 20 are added for the heel back pads, and these are supplied with hydraulic power through the flexible hoses 22. The flow diagram of the machine is described later.

In FIGS. 2 and 3 of the drawing the actuator 20 is shown applied'to a highly adjustable shoe pad of the type described in my prior Patent No. 2,863,161 granted December 9, 1958, and entitled Adjustable Shoe Pad Assembly. Referring to FIG. 3, this comprises a base 62 carrying a toe support 64, a shank support 66, and a heel support 68. The toe support 64 is adjustably pivoted at 79, that is, the pivot rod 70 may be raised or lowered in slots receiving the same by loosening lock nuts at the ends, as will be seen from inspection of FIG. 2. The angle of the toe support may be adjusted by rota-ting a handwheel 72 which turns a screw 74 to move a block 76 in horizontal direction along base 62. This block carries a screw 78 which slides against the bottom of toe support 64 and so determines the angle thereof.

The shank support 66 may be raised or lowered, and for this purpose a handwheel 80 rotates a screw 82 which moves a wedge 84 horizontally along the base. This in turn supports an inverted or mating wedge 86 formed at the bottom of the shank support 66.

The heel support 68 is pivoted on a vertically adjustable rod 88. The position of support 68 is further adjusted by means of support screws 98.

For the present purpose the toe support receives a toe pad 92 molded out of rubber or other yieldable material, and the shank support 66 receives a pad 94 of similar material. If desired, these pads may be combined into a single pad. In either case it will be seen that in combination they provide pad surfaces which are shaped to bear against both the sole and the heel breast flap of a ladies shoe.

The usual heel pad disposed on support 68 beneath the heel of a low heeled shoe is here omitted, and instead the support 68 is used as a mounting for the actuator 20, which in turn carries the heel back pad 96. The latter is made of molded rubber or equivalent yieldable material fitted around a core 98 which is secured at 100 tothe plunger =or piston rod 102 of actuator 28. The latter may be single acting, and is supplied with hydraulic fluid through flexible hose 22 leading to a pipe fitting 104 at the rear end of the cylinder. The cylinder is provided with trunnions 106, and these are received in the side plates 108 of a frame which may be formed integrally with or which may be welded or otherwise secured to the rear end 110 of the heel support 68. The pivot action at 106 permits the actuator and heel pad to tilt bodily, so that the heel back pad 96 may seat itself most efleotively against the heel, here indicated by broken line 112.

It is convenient to limit the tilting action so that the pad 96 will not turn all the way up, thereby slowing the work of the operator, and for this purpose a U-shaped member 114 is secured to the side plates 108 at 116-. The permitted tilt may be made adjustable by using a stop screw 118 and a lock nut 120.

The longitudinal position of the heel back pad 96 may be adjusted somewhat by changing the mounting of the pad on the piston rod 102. The connection is a screw connection, and this afiords a change of adjustment. However, if a larger range of adjustment is desired, the entire actuator may be mounted for bodily adjustment toward or away from the shoe, and such an arrangement is shown in FIG. 4 of the drawing. In this case the actuator 20, pipe connection 104 and trunnions 106 all correspond to those previously described. The heel pad 122 in this case is mounted in a metal holder 124 secured at the forward end of actuator plunger 126. Rotation of the heel pad may be prevented by the addition of one or more slide pins 128, the forward ends of which may be screwed into the holder 124, and the rear ends of which are slidable relative to the body of the actuator.

In the present case the trunnions 106 are received in the upper ends of arms .130, which are provided at 132 on the base of the adjustable shoe pad. At an intermediate point the arms receive the trunnions 134 of a block 136 which receives a screw 138 carrying an adjusting nut 140. The head of screw 138 is pivotally secured at 142 to a part 144 of the shoe pad. With this arrangement it will be evident that tightening the nut will move the actuator 20 toward the shoe, while loosening the nut 140 will move the actuator away from the shoe. Such adjustment is convenient in accommodating shoes of different size, style and type. The self adjustable tilt of the actuator on trunnions 106 is retained.

The operation of the machine may be further explained with reference to the flow diagram shown in FIG. 5 of the drawing. This corresponds largely to the flow diagram in FIG. 5 of my aforesaid Patent No. 2,843,864, and a detailed description is not necessary because reference may be had to the aforesaid patent. The change is in the addition of the horizontal actuators 20 with their flexible hoses 22, valves 24, and pipes which are connected to the lower ends of the main cylinders so that the actuators 20 are operated simultaneously with the main cylinders, and by means of pressure fluid having the same pressure. To simplify the diagram, the actu-.

ators 20 have been shown extending sideward instead of longitudinally of the shoe, but it will be understood that the showing here is merely schematic.

In FIG. 5 the single pump is shown at 260, and is preferably immersed in the tank of fluid as indicated at 262. The inlet is taken through a sieve 264, and is delivered to a spring accumulator 266, which may also be immersed in the fluid. The purpose and design of this accumulator are described in greater detail in my Patent No. 2,783,486 issued March 5, 1957. The pump output is also connected through pipe 268 to a pressure relief valve 270, the control handle 244 of which is located in front of the machine for ready adjustment. Overflow from the relief valve is returned to the main body of fluid 262 through a return pipe 272. The pump 260 is driven by an electric motor 274.

The pressure fluid is connected through pipe 276 to a first valve 278 for cylinders 280 (and 20) at one station, and to cylinders 282 (and 20) for the other station through a pipe 284 and valve 286. These valves are preferably solenoid actuated, as is indicated by the solenoids 288 and 290. In one position of the valve 278 the pressure fluid is connected through pipe 292 and check valve 294 to cylinder 280. In the opposite position of the valve 278 the cylinder 280 is relieved through pipe 296,,valve 278, and drain pipe 298, and it should be noted that this circuit bypasses the check valve 294.

The valve and pipe arrangement for the cylinder 282 is symmetrical or corresponds to that for cylinder 280, and no further description is believed required. It will also be understood that the check valve 294 prevents any lessening of pressure in clamp cylinder 280 (and 20) when pressure is first applied to clamp cylinder 282, and conversely the check valve 344 of clamp cylinder 282 prevents lessening of pressure in the latter when clamp cylinder 280 is first actuated.

Because of the check valves it is not possible to drain the cylinders through the B ports, and it is for this reason that separate A ports are provided, with connections which bypass the check valves, thus draining the cylinders.

The treadles 44 and 46 are connected to their respective timing clocks 50 and 52, and the latter are connected to the solenoids 288 and 2% of the solenoid valves 278 and 286. When the valves are closed the spring accumulator 266 is charged. When a valve is opened there is a rapid supply of fluid at low pressure from the accumulator. This is adequate to quickly move the pads and shoe to desired position. The pressure then builds up to the maximum or squeeze pressure. For a still more detailed description reference may be made to my Patents 2,783,486 and 2,843,864 above mentioned. Here the rapid preliminary low pressure movement has an important additional advantage in permitting relative adjustment of the sole and heel actuators before the high pressure squeeze is applied.

Another form of the invention is illustrated in FIGS. 6 and 7 of the drawing. The main sole laying machine of FIG. 6 is essentially the same as that previously described, although the configuration has been modernized by substituting an upright post 152 with a cross beam 154 cast integrally with or rigidly secured to the post v152, in lieu of the inverted U-shaped frame 34, 36 shown in FIG. 1. As before, there are two stations with upright hydraulic cylinders in base 156, which base again acts also as a fluid reservoir. The stations are controlled by foot treadles 158 and 16%). The working pressure may be adjusted by a relief valve 162. The left station is shown without a shoe and down, while the right station is shown with a shoe 178 on a last 172 raised to the stop posts 174 and 176. These are mounted on a rail 178, and may be adjusted both horizontally and vertically to fit diiferent shoes. The pressure gauge is shown at 186, and emergency release buttons or safety buttons are marked 182. The adjusting dials for the clocks or timers are shown at 184. The flexible hoses 186 lead to actuators 188 which are pivotally mounted at 190. Control valves 192 are provided ahead of the hoses 186.

The arrangement therefore is the same as previously described, and its operation is the same as previously described. The flow diagram given in FIG. 5 is fully applicable to the shoe machine of FIG. 6, except for appropriate change of reference numerals.

However, FIGS. 6 and 7 illustrate an important difference in respect to the shoe pads, and in their relation to the machine. Instead of solid rubber or equivalent yieldable material, the present machine uses two relatively movable fluid filled pads for each shoe. The first pad 208 is shaped to bear against the sole and heel breast of a shoe placed thereover, and for this purpose the bottom wall 202, two side walls 204, and one end or outer wall 2% are all rigid, and are preferably a metal casting. The top wall .208 and the inner end Wall 210 (FIG. 6) are yieldable, being for example laminations of rubber which are tightly secured to the cast body, as by means of flexible metal strips 212 (FIG. 7) and a continuous series of bolts 214. A wire may he placed beneath the strips 232 to act as a ridge for better sealing action. An additional sheet of rubber or leather 216 may be put into position to take some of the friction and wear, and to shield the upper ends of the bolts 214.

The second pad 220 is shaped to bear against the back of the heel of the shoe. Here again there is a cast body and a yieldable covering wall or diaphragm secured with a leakproof fit by sealing strips and a series of bolts or screws. The pads are relatively movable, and in the 6 present case it is the heel pad which is slidably mounted. Referring to FIG. 7 the base 202 of the pad has outwardly projecting flanges 222 which are received beneath rails 224 mounted in position by screws 226. In the case of the pad 2% the parts 224 act as clamps to lock the pad in position. Any other desired mounting means may be provided. In the case of the heel pads, the parts 224 are dimensioned to fiord a clearance for sliding action.

In FIG. 6 there are pull springs 228, the left ends of which are connected to the heel pads, and the right ends of which are connected to the stationary base, so that the springs serve to pull the heel pads to retracted position when pressure on the actuator 188 is released.

in the present case the pads are liquid filled, and the liquid may be water. The liquid may be filled through fill plugs 2369 which act also as check valves.

In order to provide the desired movement of one pad relative to the other, they are preferably made completely separate from one another, but the pressure inside the pads is maintained equal as though they were a single pad. For this purpose sole pad 2th) and heel pad 221) are connected by a flexible hose 232. A similar hose is provided for the pads at the other station, but it is not visible in FIG. 6 because it is on the outer side of the pads. It will be evident that a hose connection between pads, such as that shown at 232, serves to maintain exactly equal pressure in both pads acting on a single shoe. This alone helps guard against possible damage or breakage of a heel.

Additional safeguard in this respect is provided by the two-stage hydraulic action illustrated in FIG. 5 of the drawing. When a station is actuated the large rapid supply of liquid from the accumulator 266 causes a rapid rise of the shoe and a rapid forward movement of the heel pad. Although the latter movement is smaller than the vertical movement, there is no tendency to damage the shoe because the force exerted at this time is low, and as soon as the heel pad bears against the heel of the shoe, the remaining fluid is diverted to the main cylinder and helps raise the shoe. Moreover, by adjusting the valve 192 leading to the heel pad actuator, the motion of the latter may be slowed for better timing relative to the vertical motion produced by the main actuator. A high pressure is exerted only in the form of a squeeze after all of the parts have settled into their final position, and at that time there is no tendency to damage the shoe because the squeeze pressure is exerted equally in all directions.

The interconnection of the two actuators means that the hydraulic pressure in both is maintained alike, and the hose connection between the sole and heel pads means that the direct surface pressures applied on the shoe are maintained alike.

If it be desired to use the machine for ordinary sole laying, the valve 24 may be closed completely, and the shoe pad may be removed and replaced by an ordinary one.

It is believed that the construction and operation of my improved machine for sole and heel breast flap laying, as well as the advantages thereof, will be apparent from the foregoing detailed description. It will also be apparent that while I have shown and described my invention in a preferred form, changes may be made in the structures shown without departing from the scope of the invention, as sought to be defined in the following claims.
